2"Claim's.

My invention relates to atomizers for'peri'umes and similar fluids.

The primary object -of -my invention is to provide an atomizer which issimple and easy to operate, and which can be made inexpensively and froma few parts, -all of which may be produced by the screw machine processand without bending or soldering.

A further object :of the invention is to provide an atomizer in whichthe fluid supply chamber is shut off when the device is not in use, andin which operation of the device automatically establishes communicationwith such chamber.

A further object of the invention is to provide a mechanism of this typein which a novel and extremely eicient arrangement for breaking up thestream of perfume into a spray or mist, or in other words for reallyatomizing the perfume, is provided.

Further objects and advantages of the invention will appear amore fullyfrom the following description, particularly when taken iin conjunctionwith the accompanying drawing which forms a part thereof.

In the drawing:

Fig. 1 is a side elevation of an atomizer embodying my invention, withthe top removed.

Fig, 2 is a vertical cross section.

Figs. 3 and 4 are Vcross sections on the lines 3-3 and 4-4 respectivelyof Fig. 2.

Fig. 5 is an enlarged perspective View of `the atomizing member. g

As shown in Fig. 2, the atomizing mechanism comprises a body portion orcasing 2 having a chamber 4 therein Yfor receiving the perfume or otherfluid Ato be atomized. This vcasing is provided in its top with an.opening 5 in which may be threaded a piston member vBxl'iaving adownwardly extending portion I6 which fills and closes the opening 6. Awasher I2 of rubber or other suitable material may be placed between thebottom of the piston member 8 and the top wall of casing 2 in order toseal the joint therebetween.

Below the extension l!) piston member 8 has a further extension I4 ofsmaller diameter, also externally threaded, and smaller than aperture 6.On this member Id. is threadedly secured a tube I6, the lower portion ofwhich is iirst tapered inwardly as at I8 and then has a smallerdownwardly extending portion 2D which extends almost to the bottom ofchamber 4. Within the tapering portion I8 is a ball 22 acting as a valvefor which the tapering portion I8 forms the seat, and above this ball isa perforated retaining disc 24 suitably arranged to prevent the escapeof the ball and `to ac t as a support for the spring to be describedbelow.

The upper centralportio'n 26 of the :member 8 acts as a piston, and`outside of this portion is 4'5 an annular groove 28 and an annularouter wall or guide wall 38, integral with piston portion 26. Verticallyslidable in'the annular groove .28 is a cylinder member 32, which iits-tightly within the groove and forms with piston member :8 a 10 space 34cooperating as a cylinder with the piston portion 26. The top of thecylinder space 34 is closed by a wall 36, which is preferably rounded ontop to provide a suitable smooth surface for operation by the finger ofthe user. T5

Piston member 8 is provided with a vertical central passage 38 throughwhich extends a rod 40 slightly smaller in diameter than passage 38, andthreaded at its upper end in the top wall 36 of cylinder 32. The lowerend of rod 40 ex- 20 tends through tube or pipe I6, and is provided nearthe top of that tube with an annular flange 42 of greater diameter thanpassage 38. v.A coil spring 43 is arranged in vtube il'li, resting .atone end on plate 24 and at the other lend engaging "25 flange 42. Thediameter `.of flange 42 is somewhat less than the inside diameter of'tube I6, or in any event is so arranged that fluid may pass upwardlythrough .the tube, and also through passage 38, without interferencefrom "3b flange 42 except when the saine is in its raised positionagainst the bottom of member "8.

From the .cylinder 34, iiuid .may escape through passage 44 into recessl46. Recess y46 extends out to one side of top wall 36, :and with- 35 inthe recess is arranged a nozzle member 48 having a nozzle opening 50 ofvreduced .size to permit the escape of V'atomized uid. The member 48 hasa tube-like portion 52 extending with'- in tlie Ibore 46, and withinportion `52 and the -40 bore is arranged a helix 54 (Fig. 5) whichsubstantially lls the borre, and which consists of a plug or rod, ofsubstantially the same diameter as extension 52, and provided with apair of helical grooves in its surface. By this construc- 45 tion, thefluid passing through the bore is forced to follow the configuration ofthe helix. This imparts a swirling motion to the fluid and causes it tobe atomized or broken up into a ne mist as it leaves the nozzle aperture50.

The atomizer may be closed and covered when not in use by a cap or cover56, which may be threadedly secured on the base or reservoir 2.

'Ihe operation of the device is very simple. The wall 32 iits veryclosely Within the groove 28, 55

so that the connection is substantially air-tight, or at leastsuiciently so for the operation of the device. If the cylinder member 32is depressed with the finger, ball 22 will be in its lowered positionand the air in the cylinder space 34 will be forced out through nozzle48. When the pressure on the top 36 is released, the cylinder member 32will rise suddenly and will create a reduction in pressure in the space34 which cannot be immediately relieved through opening 50. This willcause some of the perfume to be raised up through tube 20 and pastone-way ball valve 22 into the section I6. As this operation isrepeated, the section I6 will gradually be filled and then perfume willbe finally brought up intoy the chamber 34. Of course in continuedoperation thereafter each use of the atomizer will 'draw in more of thefluid and will thereby replace in the chamber 34 perfume which may havebeen removed therefrom.

AsA soon as the perfume is present in chamber 34, depression of member36 will cause the perfume to be ejected through helix 54 and nozzle 50in a fine spray. This perfume then escapes from the device in atomizedcondition as is desired.

Each time the member 36 rises under the action of spring 43, the flange42 will be pressed against the bottom of the piston member 8 and therebywill close the lower end of passage 38. This will seal within thecontainer all perfume below this level and will prevent losses byevaporation of any large quantities even though the device may stand forsome time without use.

In order to ll the atomizer, the piston member 8 may be unscrewed as awhole, and the fluid poured through opening 6 into the reservoir.

Member 3 may then be replaced.
